Genesis dropdown menu conflict

Hi guys!
Wanted to report a strange issue I see on a dev site (unfortunately onboard, so I can′t provide a link) running on Genesis (using a childtheme). There are currently only four plugins and by deactivating/activating them one by one, I was able to narrow the issue down to RFWBS.

The subitems in my dropdown menu only show up when hovered the very first time. After that, they won′t show no more. Using Firebug, I noticed that the sub-ul gets transition and opacity settings (set inline by the script) it doesn′t get normally. This seems to come from the slider.

Newest Genesis is using superfish.min.js?ver=1.7.4, superfish args are delay:100,animation:{opacity:”show”,height:”show”).
Not sure if this would happen in other themes using superfish, too, or if it′s a problem only related to Genesis and the CSS classes in use, maybe.
Hoping it might help, I made a screenshot:

Any idea for this one? I′m really pleased with your plugin so far, so I hope to get this solved…
